    What is Keratoconus Disease?

    Keratoconus is a disease in which the Cornea tissue, known as the transparent layer of the eye, becomes pointed, curved forward and thinned. Since this deformity in the cornea causes myopia and irregular astigmatism, it causes loss of vision and deterioration in the quality of vision. In this disease, which can be seen in both eyes, one eye may generally be affected slightly more than the other.

    Who Gets Keratoconus Disease?

    Although the exact cause of keratoconus disease is unknown, genetic predisposition and mechanical trauma such as frequent rubbing of the eyes can be considered among the important causes.  The disease usually begins to appear around the age of 12-13 and may continue to progress until the age of 40. The keratoconus patients we encounter in the clinic are usually people who change glasses frequently and are prone to allergic conjunctivitis. This disease is more common especially in people living in dry, windy and dusty environments.

    What are the symptoms of Keratoconus?

    One of the earliest symptoms of keratoconus is frequent changes in eyeglass prescriptions. It is not possible to achieve completely sharp vision with these changed glasses. Since the shape change that occurs in the cornea as a result of the cornea bulging forward creates personal myopia and irregular astigmatism, it is not possible to fully correct this with glasses.

    How Do We Diagnose Keratoconus Disease?

    We can easily make the diagnosis with a corneal topography test after a detailed vision examination.

    Treatment for Keratoconus Disease!

    There is no complete treatment for keratoconus disease. All treatment options are aimed at stopping the progression of the disease and eliminating visual impairment.

    If we examine the treatment options in keratoconus disease step by step, it is possible to increase visual acuity with glasses in very early stage keratoconus patients. It is possible to evaluate disease progression with corneal topography tests performed every 6 months.

    In more advanced stages of the disease, it may not be possible to increase visual acuity with glasses, in which case special contact lenses (Hybrid, scleral or rigid gas permeable) can be used to increase visual acuity. If we decide that the disease is a progressive disease, then we apply Cross-linking treatment. If we cannot benefit from contact lenses and glasses in improving visual acuity, it is possible to benefit from Corneal Ring treatment. Corneal transplantation, which we call Corneal Transplantation (PKP, DALK), can be performed in very advanced Keratoconus patients.

    In summary;

    • Glasses or Contact lenses in the early stages
    • In more advanced stages Corneal Ring
    • Cross-linking treatment to stop disease progression
    • In end-stage disease, Cornea Transplantation can be performed.
